VALVE.

Specification of Letters Patent.

Patented July so, 1918.

Application filed November 14, 1916. Serial No. 131,298.

To all whom it may concern:

Be it known that we, EDWARD B. LonnNzEN and CHARLES LORENZEN, citizens of the United States, residing at Lorain, in the county of Lorain and State of Ohio, have invented new and useful Improvements in Valves, of which the following is a specification.

This invention relates to certain improvements in valves of the reciprocating type, and aims to provide a valve of this character wherein the use of packing is eliminated, and at the same time leakage effectually prevented.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the preferred form of the invention herein illustrated, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this specification like numerals of reference indicate similar parts in the several views and wherein Figure 1 is a vertical sectional view taken through a valve constructed in accordance with our invention.

Fig. 2 is a View partly in section taken on line a-a of Fig. 1.

Fig. 3 is a horizontal sectional view taken on line bb of Fig. 2.

A valve constructed in accordance with our invention embodies a casing 10 which as shown is of usual design, but which may vary in this respect if so desired. The casing is provided with an inlet port 11, and an outlet port 12, the respective ports being interiorly threaded as shown. The upper end of the casing is open and interiorly threaded to accommodate the main body portion 13 of a bonnet, which main body portion is threadedly associated with the casing in the manner illustrated. The bonnet includes a centrally disposed tubular member 1 1 provided with an interiorly extending flange 15 arranged at an appropriate point in its length. The tubular member 14 has positioned therein below the shoulder 15, a sleeve 16, which is carried by a threaded valve stem 17 which projects through the tubular member from a point above the shoulder 15 throughout the adjacent end of said member, the stem being held in position by means of lock nuts 18 threaded upon the stem and resting upon the upper extremity of the tubular member 14. The sleeve 16 is mounted for rotation within. the tubular member, and such movement is imparted thereto through the instrumentality of the wheel or manipulating handle 20 secured upon the stem 17. The sleeve 16 is interiorly threaded for a portion of its length as at 21 to adjust-ably receive the threaded stem 22 of a disk valve 23 which latter normally engages its seat 241. Manifestly by reason of this construction and arrangement of parts, the valve 23 is moved toward or away from its seat as'the occasion may require, by rotating the stem 17 in either one or the other direction, which causes the stem 22 to move in a proper direction within the sleeve 16.

With a view of eliminating the packing that is generally employed with valves of this type, and at the same time effectually prevent leakage, we taper the interior wall of the tubular member 1 1- an appropriate distance, and correspondingly taper the exterior wall of the sleeve 16 to provide for the proper fit between these parts when the latter are operatively associated. Encircling the stem 17 is a coil spring 26 having one end bearing against the shoulder 15 and its opposite end bearing against the adjacent lock nut 18, the spring possessing the requisite strength to accomplish its function of holding the sleeve 16 in effective engage ment with the tapered wall of the tubular member, and thus obviating longitudinal movement of the sleeve within the tubular member under all and any conditions. This fact facilitates the opening and closing of the valve, and renders the structure in its entirety positive in its operation. It will be noted that the tubular member 16 has its end adjacent the shoulder 15 spaced an appreciable distance from the latter to permit the member 16 to be adjusted from time to time to compensate for wear, which necessarily takes place between the tubular member 16 at its point of contact with the portion 13 of the bonnet. For the purpose of carrying this idea into effect we arrange the tubular member 16 in the manner so that the tapered portion thereof projects a considerable dis tance beyond the lower extremity of the bonnet. Manifestly, as wear takes place between the tubular member 16 and the portion 13 of the bonnet, the nuts 18 can be adjusted upon the stem to bring the tubular member 16 closer to the flange 15, during Which operation the tapered portion of the tubular member 16 is again brought into contact With the bodynpo'rti'on 13 of the bonnet, to provide a fluid-tight joint between said parts.

At diametrically opposite points, the cas ing ,10, isprovidednvitlr.ribs 27, wh-iehare received between spaced ,lugsQSformedon. the valve, for the purpose of guiding the valve in its movements. toward and ,away from; its seat, and preventing any p ssibility, of the valve rotating ,during its adjustments;
